Many bus lines like the 22 and 14 follow pretty much the same routes as their streetcar predecessors. The proto-24 was a Divisidero-only line that stopped before Haight (I’m guessing they extended it through Noe once they shut down the Castro cable car line.)

As for the other streetcar lines in the Mission, our beloved 26 ran down Guerrero instead of Valencia (until 18th where it switched over to Mission). In this 1928 photo from the SF Public Library, we see the 26 (and 10) tracks running down (a not-yet-widened) Guerrero and 28th with San Jose Ave breaking off to the right (site of the soon-to-be Pavement-to-Parks plaza).

There was a 9 line that ran down 29th to Mission and then continued on Valencia to the ferries. We’ve previously seen this 1948 shot of the 9 in front of the old Lyceum Theatre (aka Safeway).

Below we have the 9 stopped on 29th, right before Mission (we are looking down 29th to the west). The 3300 Club would be the building on the left, and the Front Porch would be a few buildings down. The buildings on the right no longer exist – the 199 Tiffany building is there now, and Goood Frikin Chicken would be on the right. (Progress!!)

The location of the 9 line photo below is not labeled on the SFPL site, but I am fairly certain this is looking north on Valencia, right after it merges with Mission. If so, that’s Duncan and St. Luke’s on the left.

Here is the intersection of Valencia and Mission in 1945 — the shot above would be to the left. The tower on the right is the Sears building.

That two block stretch of Dolores without the raised grass median strip between 22nd and 24th Streets was because a street car ran there. It ran west on 22nd to Dolores, then south to 24th and west on 24th through Noe Valley.
